使用AnolisOS-7.9-RC1-aarch64-dvd.iso装机后的anck环境kdump自启动异常，且使用systemctl restart kdump也启动不了 ------------------------------------- [root@localhost ~]# systemctl --failed UNIT LOAD ACTIVE SUB DESCRIPTION ● kdump.service loaded failed failed Crash recovery kernel arming LOAD = Reflects whether the unit definition was properly loaded. ACTIVE = The high-level unit activation state, i.e. generalization of SUB. SUB = The low-level unit activation state, values depend on unit type. 1 loaded units listed. Pass --all to see loaded but inactive units, too. To show all installed unit files use 'systemctl list-unit-files'. [root@localhost ~]# [root@localhost ~]# systemctl restart kdump Job for kdump.service failed because the control process exited with error code. See "systemctl status kdump.service" and "journalctl -xe" for details. [root@localhost ~]# uname -r 4.19.91-25.an7.aarch64 [root@localhost ~]# cat /etc/redhat-release Anolis OS release 7.9
